§ 152.071  SANITARY SEWERS.
   (A)   Sanitary sewer utility systems shall be constructed in accordance with the General Notes (Sewer) contained in Appendix D attached to Ordinance 96-106, and the standards drawings and specifications of the village.
   (B)   Each lot shall be served by an adequate sanitary sewage collection and disposal system. Evidence that the sewer construction plans have been reviewed and approved by Ohio EPA and the Village Engineer shall be submitted to the Village Manager prior to approval of the final plat.
   (C)   (1)   All sanitary sewer pipe shall be extra strength vitrified clay, reinforced concrete, ductile iron, or polyvinyl chloride (minimum SDR 35). All pipe shall have sufficient strength to withstand an HS-20 live load. If PVC pipe is used, a mandrel test is required just prior to expiration of the one-year guarantee to assure maximum deflection of 5% has not been exceeded. Any pipe that fails this test will be replaced at the subdivider’s expense.
      (2)   Reinforced concrete pipe and structures, and PVC pipe, shall be shop tested at the direction of the Village Engineer at the subdivider’s expense. A report of the material tests shall be provided to the Village Engineer.
   (D)   All sanitary sewage collection systems shall be constructed in accordance with the rules, regulations, standards, and specifications of the village, OEPA, and the state’s Department of Health.
   (E)   Only under circumstances of extreme hardship shall sewage lift stations, sewage grinder pumps, or individual household sewage disposal systems be permitted and only with the approval of the Village Engineer, the County Board of Health, and the village. Where approved, such systems shall meet the standards and specifications of the Village Engineer, the County Board of Health, and the village.
   (F)   A map must be provided delineating the contributing area in acres to the sanitary sewer system. All sanitary sewer manholes shall be numbered, consistent with the numbering on the improvement plans. A copy of the location map may be used for this purpose.
   (G)   Sanitary sewers shall be designed in accordance with the following table entitled “Sanitary Sewer Design Criteria”.
      (1)   This table is based on a population density of 8.4 persons per acre (single-family, residential density) with a per capita flow of 100 gallons per day (gpd).
      (2)   For areas of greater population density than 8.4 persons per acre, the design flow shall be determined on a basis of population instead of area.
      (3)   The sanitary sewer design shall be in accordance with the current edition of Ten States - Recommended Standards for Sewage Works and the requirements of the Ohio EPA.

   (H)   The subdivider shall provide the village with all required Ohio EPA approvals and pay all Ohio EPA review fees.
   (I)   Minimum line size shall be eight inches. Downstream sanitary sewer pipe sizes shall be greater than or equal to the upstream size unless otherwise approved by the village. The flow lines of pipes shall be set such that either the crown, or the 0.8 depth points at junctions are at the same elevation. However, the crown of the outlet pipe may be lower. If larger line sizes are required to be in conformance with the Master Plan, the village may participate in the cost of oversizing, in accordance with the subdivider’s agreement.
   (J)   All sanitary sewer manholes shall be pre-cast concrete, unless otherwise approved by the Village Engineer.
   (K)   Service shall be provided to each lot. If basement service is not provided, it shall be so noted on the sanitary sewer improvement plans and on the plat. Risers shall be provided where the service is greater than 12 feet deep, provided that basement service will still be provided.
   (L)   All sanitary sewers shall be visually inspected and the inspection recorded on appropriate digital media after construction prior to acceptance of the sewers by the village. The videotape shall remain the property of the village. The videotape shall clearly identify the location of the camera within the sewer, date and time of videotape, and be of sufficient quality to determine the condition of the sewers.
